Abstract
Apparatus especially X-Y plotters having a marking device for marking a surface. A support is provided for supporting the marking device. The support is movable along an axis of the housing while the marking device can be selectively raised and lowered relative to the surface. The raising and lowering is carried out by means of a flexible driving element, for example, a cable, connected to a pivotable link on the support and activated by a motor. The marking device support is freely translatable relative to the flexible driving element.
